Hecke-Clifford代数与Spin Hecke代数IV:奇双仿射型

Hecke-Clifford Algebras and Spin Hecke Algebras IV: Odd Double Affine Type

Ta Khongsap, Weiqiang Wang

摘要:

引入了由经典外尔群W和两个反交换生成元的斜多项式子代数生成的奇双仿射Hecke代数(DaHa).证明了该代数与由W和两个多项式Clifford子代数生成的另一个新的DaHa是Morita等价的。还有第三个代数包含一个自旋外尔群代数是Morita(超)等价于上述两个代数。我们建立PBW性质和构造Verma型表示通过Dunkl算子为这些代数。

英文摘要:

We introduce an odd double affine Hecke algebra (DaHa) generated by a classical Weyl group W and two skew-polynomial subalgebras of anticommuting generators. This algebra is shown to be Morita equivalent to another new DaHa which are generated by W and two polynomial-Clifford subalgebras. There is yet a third algebra containing a spin Weyl group algebra which is Morita (super)equivalent to the above two algebras. We establish the PBW properties and construct Verma-type representations via Dunkl operators for these algebras.
